Abstract

A data mapping management server (72) collects data mapping information about functions for providing virtual storage regions, and provides an administrator with a management view on which the virtual storage regions created/managed in each virtual storage region providing function can be comprehensively grasped based on the collected information. The order to migrate data with the destination after mapping alteration can be accepted on interactive views. The data mapping management server (72) produces a procedure plan for carrying out the accepted data mapping alteration order, and presents it to the administrator. The administrator decides if this plan can be carried out. If the administrator permits this plan to be carried out, the server orders each virtual storage region providing function to migrate data and create new virtual storage regions according to the produced plan.
